The original speaker was gutted, as I wrote above. The end of the field coil enclosure and mounting bracket closest to the cone was drilled out to make room for the magnet of a PM speaker fastened into the old basket.
Yes, I should have written about the Henries, and I do have a meter to measure Henries, but do not know the specification of the original in Henries, just the DC ohms listed on the spreadsheet. There is no way the one winding of the small transformer the hack used would have the same rating in Henries as the large old field coil.
